RSA operations.

This group of functions is used for RSA with padding. / /@{*/ / RSA PKCS1 V1.5 encryption.

The message * m - is encrypted to a ciphertext returned in * c - .

• c - The generated ciphertext.
• c_len - Length of * c - .
• m - The message to be encrypted.
• m_len - Length of * m - . 0 <= m_len <= key-size - 11.
• seed - The random seed to be used for the padding.
• s_len - Length of * seed - . * s_len - >= key-size - 3 - * m_len -
• pk - A valid RSA public key.
• mem - The working memory. Length OCRYPTO_RSA_PUB_MEM_SIZE(bits).

Returns -1 If the message is too long (m_len > key-size - 11). Returns -2 If the seed is too short (s_len < key-size - 3 - m_len). Returns 0 On success.

@remark The key * pk - should be initialized with * ocrypto_rsa_init_pub_key - . @remark The * seed - should consist of non-zero random bytes. @remark * c - may be same as * m - or * mem - .
